MACHINE FOR COVERING FIBTROUS OR METAL CORES.

SPECIFICATION forming part of Letters Patent No. 540,048, dated May 28, 1895.

Application filed May 17, 1892.

To all whom it may concern.-

Be it known that we, PETER DEISSLER and WILLIAM DEISSLER, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,

have invented certain new and useful Improvements in Machines for Covering Fibrous or Metal Cores; and we do hereby declare the following to be a full, clear, and exact descrip- [0 tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has relation to covering cores of fiber or metal with suitable material such as making gimps, cords or other like articles; and ithas for its object a simple and efficient machine for covering the cores or material to be operated on, which admits of economically producing a better and more even article and a greater output than heretofore, and by means of which a large variety of difierent kinds of goods can be turned out by one or the same machine. I

Our invention accordingly consists of the 2 5 combinations, construction, and arrangement of parts, as hereinafter more particularly set forth in the specification and pointed out in the claims.

Reference is had to the accompanying drawings, wherein- Figure l is an end elevation of a gimpingmachine embodying our improvements. Fig. '2 is a sectional front elevation of part of the machine, showing the operation of gimping.

5 Fig. 3 is an elevation of the thread or bobbin holder for the core-cover threads, detached I from the machine. Fig. at is a plan of such spools or bobbins with a form of guide-rolls or appurtenances conducting the threads on the bobbins or spool to'the contractor or the core-guide. Fig. 5 is a transverse vertical section; Fig. 6, a partial plan. Fig. 7 is a plan, drawn to an enlarged scale, of the core or warp spool-holding frame, with tension device for the core and guide-hook and roller for preventing the twist in the warp or core passing back to the threads or the core on the bobbin, said warpspool-holder being detached from the machine. Fig. 8 is an elevation of said guide-hook and roller detached from said warp-spool-holding frame. Fig. 9 is'a view Serial No. 433,364:- (No model.)

similar to Fig. 4 drawn to an enlarged scale and partly sectional. Fig. 10 is a partial side elevation of the core-guide, partly broken away, and showing more plainly the contractor thereon for the cover-threads for the core.

In the drawings, the twisting, covering, feed-regulating and take-up mechanism are shown arranged in a vertical position in a housing or frame A, a preferable form, on account of compactness, ease of handling by and less liability of danger to the operator, and ease of motion for obtaining higher speed of said parts. may be horizontally or otherwise arranged as desired.

The core or warp spool frame B, as shown more plainly in Figs. 2, 5 and 7, has tubular journals b and b mounted in brackets a. aat the top of the frame A; the upper journal 1) of which has, as shown, a cone pulley and belt connection a and a? respectively, with a like pulley a on a drivingor counter-shaft a.

Suitably mounted in frame B so as to be readily detached therefrom is the warp or core spool 0 having a reciprocating tension plate a with actuating spring a surrounding the rod 0 which passes through the tubular shaft or journal 1). The tension-plate c bears directly on the warp core or threads preferably, and its action is direct so thatit prevents the warp or core threads passing off of the bobbin 0 faster than the take-up of the finished product, as hereinafter described, and thereby avoid imperfection in the formation of the goods.

In the form of tension device in the drawings, variation in spring-pressure is obtained by substituting springs of varying strengths on the rod or stem 0 Beneath the bobbin or spool O onframe B is a'rod 0? upon which is loosely mounted a guide-roller c and a fixed hook 0 The roller and the hook c is in line with and projects within or over part of the groove or one end of the roller as shown, so as to contract and guide the warp threads or core w from spool O to the roller 0 around which they pass once and are then cond ucted through the tubular journal I) of frame B as indicated more plainly in Fig. 5. After emerging from said journal,

If desired,'however, said parts 0 preferably has end flanges or is grooved,

the condensed or formed ,core or warp w is conducted to a fixedguidel), carrying a eontractor of wire or other formation d as deemed suitable, and having at the covering point thereof for the core, a curved surface or sur- -1"aces d d which form spreaders for obtaining a more even layer and larger spread of the cover threads for the core as they are Wound or spun thereon.

Adjacent to the core guide D is a suitable fixed frame F for holding the cover thread bobbins or spoolsffrom which threads 2 are conducted by suitably located guiderollersf f to the contractor d on the core guide D,

said threads being spread out over the core by the curved surface d of the guide for-being wound upon the warp or core passing throughor over the guideand rotating thereon.

the machine in any desired manner. In this instance the'studs of the rollersare supported in the horizontal limb ofa depending shaped bracket f which is secured to an .ad-

jacent part of the frame. lSy this construction itwill be noted that the-cover threads vdo not revolve around the core or warp threads as heretofore, but that the core or warpis positively rotated, and in doing so winds' or spins the cover threadsz upon it, the pointof winding of the cover threads upon the core being at the curved surfaces orspreaders d' -0n the guide D. The finished goods m l-after leaving the guide ,D .is conducted to the feed regulating device G which controlsthe .amount of coreor warp threads withdrawn vided with'a worm wheel g meshing with a -fixed screw H whereby as frame 9 rotates the worm-wheel g is actuated .to impart a feed motion to the-roller g to. feed the warp threads from the spool O in frame B .andover the guide D as the core orwarp threads arecovcred.

The worm H is secured to or forms apart of a tubular bracket h surrounding journal 9 of :frame G, and issecured tothehousing A as indicated at h. 'The journal g iscontinued throughbracket h and joins the takeup frame I to connectit rigidly to said frame G so thatboth will #revolve in unison. The frame I has a step, bearing at 11. in. housing A .as shown moreplainly in Fig. 1. Tlhe frame Iatits upper end on one side carries a shaft iprovided with .a worm wheel vt engaging .with a fixed wormHf on the tubular bracketih.

The said frame F and the guiderollers .20 f'f are secured to the housing or frame of "nection m from shaft a as that of the feed and take-up devices.

the core or warp is to be twisted, then the frame B is rotatedata slower or greater speed See more plainly Fig. 2. Shaft t" has prefer ably ateach end a gear or train of gear connection 'F with a double reversescrew shaft K energizing a movable eye or carrier is hung or loosely supported upon a cross-bar or bars so that a rotary movement of shaft'i imparts by means of screw K a to and fro motion transversely to eye or carrier to permit the bobbin L in said frame to properly wind or take up the finished product as said bobbin is rotated by means of a grooved or other wheel and belt connection Z and Z with a second Worm wheel shaft Z on the other side of frame I engaging with the opposite side of worm H on bracket h. See more plainly, Fig. 5. Re-

specting the belt connection the belt will slip as the coils of finished fabric progressively increase upon the bobbinL.

The action of the machine is as follows: The feed device Grand take-up I rotate together at one speed, by meanslof a belt conv If the core or warp is not to be twisted, the warp-holding spoolframe B revolves at the same rate of speed If than the devices G and I, this difference in thespeed produeingthe twist in' the core or warp, the differences of the slower or greater .rate of speed producing right or left twist of thewarp or core.

The covering canbe wound on the'core from either side of the guide or spreader for pro- ,ducing right or left hand goods. The twist in the warp or core is made between the curved surface or spreader d of the guide D or the point of covering of the core or warp and the roller 0 and hook c on the frame B, and as such twist cannot extend beyond said hook the .warps on the bobbin Care therefore not subject to the twisting action (see Fig. 2) and coming straight or untwisted from the bobbin to the book they do not pick up any unnecessary threads, thus avoiding'making imperfect and uneven work; and further, as the twist does not extend back of roller 0 a more even core is produced to make a correspondingly finished. fabric.

'As the covering threads .2 do not revolve, and are conducted to and over the curved surface or, spreaderd' on guide D, theyare evenly held and spread upon suchsurface to produce good and accurate winding for fully covering the core without crowding, lumping .or attenuation of the cover.

Alarge variety of goods can beproduced by changing the relative speeds. of thelwarp- .spool and take-up and feeddevices. Hence pearl, spiral ,or plain, gimps can be made, or

the warp may be covered and a second spiral .cover beput on at the same time by providving aisuitable guide therefon' In some cases, if desired, the curved surfaces or, spreaders (1' may be dispensed with,

. andwstraightor other suitable edges jsu'bstituted, but where straightv edges are used,the

'cover threads are apt and in most cases crowd up in the middle, thereby producing uneven covering, and hence the curved form of spreader as it prevents such uneven covering as heretofore described, such even spreadingresulting also in saving cover-thread stock and cheapening the cost of the goods.

What we claim is 1. In a core covering machine, the combination of a revoluble warp spool frame, having hollow journals at its ends, through one of which journals the core passes, a core spool j ournaled in said frame, a ,tension device therefor having a stem carried by the other of said journals, a guide roller loosely mounted.

nation of a ievoluble frame 13, having hollow journals mounted .in brackets of the main frame, one of said journals forming a guide for the core the spool j ournaled in said frame,

the tension plate for said spool, said plate having a stem carried by the other of said journals the loosely mounted guide roller 0 its book 0 the trough-shaped guide D, into which the core passes fromthe journal of the frame B, the fixed covering yarn spool holder, the revoluble frame g, having hollow journals and feed regulating devices, and the revoluble frame I and carrying take up devices and means for driving said framesI and g at the same speed, substantially as specified.

In testimony whereof We affix our signatures in presence of two witnesses.
